ABSTRACT
Toxics Release Inventory (TRI) is a database available to the public; it contains detailed information on toxic chemical releases by individual industrial facilities. The TRI program has been amended by the Pollution Prevention Act of 1990 and is administered by the Environmental Protection Agency (EPA). Most states allow reporters to submit both reports at once through programs provided on the EPA Web site. A facility must report to TRI if it The Pollution Prevention Act (PPA) of 1990 mandated collection of data on toxic chemicals that are treated on site, recycled, and combusted for energy recovery. For the year 2007, some 21,996 facilities reported releasing some 4.1 billion pounds of chemicals under the TRI program. The largest releases were by industrial categories that were not included in the original TRI program. TRI chemicals vary widely in toxicity or their potential to produce toxic effects. Publication of the data tends to center on total pounds released rather than toxic impact.
